Subject: [PATCH] Compile all kernels with "-ffreestanding":

	Assert that compilation takes place in a freestanding environment. This
	implies `-fno-builtin'. A freestanding environment is one in which the
	standard library may not exist, and program startup may not necessarily be
	at main. The most obvious example is an OS kernel. This is equivalent to
	`-fno-hosted'.
